Men too embarrassed to get Viagra at the store now have an alternative: buying it online.

In a first for the drug industry, Pfizer has announced they'll begin selling the erectile dysfunction pill on its website. Patients will still need a prescription, and those who order online are even eligible for discounts.

Pfizer hopes the move will help stop counterfeit online pharmacies. And healthcare experts say if it works, other drug companies are likely to join them.
